XLG® T Tripletube

Heat exchanger with three or four concentric corrugated tubes. Very suitable for processing viscous products especially in sanitary applications, although it can be also used in industrial applications.

Description

XLG®T Tripletube heat exchangers are manufactured entirely from stainless steel and consist of three or four concentric corrugated tubes.

The fluid to be treated (the product) flows through a kind of sandwich as it is heated (or cooled) from the outside and the inside annulus made by concentric tubes, while the product flows in the middle annulus formed by the 2nd and 3rd tubes.

The range is formed by units with different diameters to meet from low to high process flow rates. Tubes are corrugated to boost heat transfer and to minimize fouling.

All of our units are designed and manufactured according to the CE marking regulations contained in the European Pressure Directive (97/23/EC) and are CE marked when we are permitted to do so. Also our units are approved by the 3-A Organisation in the United States.

Materials of construction

All product wetted components (interior tube and bends etc.) are manufactured from AISI 316L stainless steel but for more aggressive fluids a range of Duplex stainless steels are also available.

The service side components are normally made from AISI 304 stainless steel but AISI 316L and Duplex steels may be used when required.

Areas not in contact with the working fluids are normally constructed from AISI 304 stainless steel.

Silicone rubber is used for the O ring seals and connection gaskets or seals but a wide range of alternative elastomers are available when specific applications require them.

Alternative materials can be offered for all wetted components on application.

Connections

To allow a rapid and flexible installation and easy inspection of the units the XLG®T Tripletube heat exchangers use DIN/ISO/ASME standard ferrule/clamp connections. If the matching ferrules, clamps gaskets are required by the client for installation purposes these can be supplied on request to allow connection to the clients' pipe work system.

Design Conditions

The standard design conditions for the XLG®T Tripletube heat exchangers are the following:
